President Trump flew into Tennessee Monday to boast about the red-hot US economy, crediting his tax cuts for fueling the record-shattering stock-market surge.

“The American Dream is roaring back to life. And we have just signed into law the most significant tax cuts and reforms in American history,” he said in Nashville at the annual American Farm Bureau Convention.

Most of the benefits, he said, went to working families, small businesses and family farmers.

He also said the tax cuts prompted companies across the US to give raises or bonuses to their workers.

More than 1 million workers have already received a tax-cut bonus, he said.

Trump took a shot at Democrats for not backing his plan and warned that if given the chance, they would raise taxes by “40, 50, 60 percent.”

The GOP’s tax overhaul has been criticized for favoring the rich, but the president insisted on Monday that it would largely benefit the middle class.

“The typical family of four earning $75,000 will see an income-tax cut of more than $2,000 each, slashing their tax bill in half each year,” Trump said.

Independent fact checkers note that while the tax cut is among the largest, others went deeper. They also say most of the benefits will go to the wealthiest Americans.

The president called his supporters “lucky.”

“Oh, are you happy you voted for me. You are so lucky that I gave you that privilege,” he said.

Trump also touted his rollback of Obama-era regulations that he said stifled business and killed jobs.

And the president revisited familiar themes, praising the flag and national anthem and police while slamming the US immigration system and the media.

“My clients do not intend to cease publication, no such retraction will occur, and no apology is warranted,” their attorney, Elizabeth McNamara, wrote to Charles Harder, one of the president’s personal lawyers, ABC News reported.

Harder had sent a cease-and-desist letter to Wolff and Henry Holt & Co. last week calling on them to halt publication of the book, which raises questions about Trump’s mental health and competence, and to retract its allegations and apologize to the president.

McNamara notes Harder failed to identify “a single statement in the book that is factually false or defamatory” and said his letter was “designed to silence legitimate criticism.”

The White House has slammed Wolff and called the book fiction. Trump has derided it as a “fake book” and defended himself by saying he went to “the best college,” was, “like, really smart” and a “very stable genius.”
